I know I can rent a kayak but would rather use my own. Anyone ever use their own kayak or canoe? Since I can't find online, I'm guessing a call to guest services is in order.
I would have no idea. I'm a friendship boat kinda guy. :] Call a resort. You'll get an answer. My guess is they will say "no" due to liability and all. I don't recall seeing any non-disney craft out there. I hope I'm wrong as I would like you to enjoy your holiday.
I don't believe it is possible since they have their own, the only place i know that does it is Fort Wilderness Campsite. You can always call and ask though.
